Description
Technical field
The utility model relates to valve technology field, relates in particular to a kind of antifreeze feed valve.
Background technique
As everyone knows, after feed valve cuts out, can retain one section water level in the ground upper pipeline below water outlet, if do not take other measures, temperature is reduced to below freezing, and this part water will be frozen, stop up water pipe even with water pipe from freezing crack, affect the normal use of water supply system.At present, the antifreeze of feed valve all is to adopt the parcel thermal insulating material usually, and this measure is neither attractive in appearance, and antifreezing effect is undesirable again, and especially in the northern area of China, winter temperature is low, and the parcel thermal insulating material does not have antifreezing effect.
The model utility content
Technical problem to be solved in the utility model is: provide a kind of antifreeze feed valve, to solve the bad technical problem of feed valve antifreezing effect.
For solving the problems of the technologies described above, the technical solution of the utility model is: antifreeze feed valve, comprise upper valve body and lower valve body, described upper valve body has a upper piston chamber, be slidingly fitted with the upper piston that is driven by straight line driving mechanism in the described upper piston chamber, described upper valve body is provided with the water outlet that is communicated with described upper piston chamber; Described lower valve body has a lower piston chamber, described lower piston is slidingly fitted with lower piston in the chamber, annular is distributed with some through holes on the described lower piston, described through hole is communicated with described lower piston chamber, described lower valve body is provided with discharge opening and intake tunnel, described intake tunnel does not have the position of through hole towards described lower piston, described discharge opening is communicated with described lower piston chamber; Described upper piston chamber is communicated with by connecting tube with the lower piston chamber, and described upper piston and lower piston link together by connecting rod, and described connecting rod runs through described connecting tube.
As a kind of improvement, the end of described lower valve body is provided with a water inlet valve plug, and described water inlet valve plug is provided with a flange, and described flange relies on the described lower piston, and described intake tunnel is arranged at described inlet valve beyond the Great Wall and runs through described flange.
As further improvement, described straight line driving mechanism comprises the handwheel that is fixedly installed on the described upper piston, and described upper piston is threaded with upper valve body.
After having adopted technique scheme, the beneficial effects of the utility model are: owing to designed discharge opening and the water outlet that is connected, and when normally feeding water, the shutoff discharge opening, current are normally fed water by water outlet through intake tunnel, through hole, connecting tube, after feedwater finishes, be communicated with discharge opening and water outlet, water in the connecting tube is discharged, do not retain, therefore can be not frozen, avoid connecting tube by bursting by freezing, overcome the defective of the normal feedwater of the frozen impact of water in the severe cold area water pipe.
Owing to being provided with into the water valve plug on the lower valve body, having simplified the structure of feed valve, so that installation and maintenance of the present utility model is convenient.
